Hitachi H8/3152 Hardware Manual page 3

Preface
The H8/3150 series is a single-chip microcomputer built around a high-speed H8/300 CPU core.
On-chip facilities include an EEPROM, a ROM, a RAM, two I/O ports, a random number
generator (RNG), and a watchdog timer (WDT).
On-chip EEPROM makes the H8/3150 series ideal for applications requiring nonvolatile data
storage, including smart cards and portable data banks. Security functions protect data in the
internal memory against illegal external reading and writing.
This manual describes the H8/3150 series hardware. For details of the instruction set, refer to the
H8/300 Series Programming Manual.
